` PAPER COVER FOR CONTAINERS.

Application led March 21, 1922. Serial No. 545,531.'

To all 'whom t may concern:

Beit known that we, JAMES E. ANNEN and GEORGE O. FRosTAD, citizensy of the United States, each residing at `-Milwaukee, county of Milwaukee, State of Wisconsin, have invented a new and useful Improvement in Paper Covers for Containers, of which the following is a full, clear, and exact description.

The present linvention relates to paper covers for containers such as paper cans. In the drawings' the invention is illustrated as applied to a slipl cover for a circular paper can.

yHeretofore in making such covers, the paper at the edge has been bent at right angles to the cover top to form the flange. The paper has a certain amount of resiliency or spring so that there has been a tendency for the flange to spring outwardly. As a consequence, slip covers 'have usually been made in two pieces, a separate piece of paper being employed for the flange. The object of the present invention is to form the flange of the same piece of material as the body of the cover, thus saving expense, and at the same time to prevent the flaring out of the flange heretofore occurring in one piece covers. To prevent this flarmg or springing out of the flange,- the paper at the base of the flange is bent or folded back so as to destroy the spring of the paper at that point.

The folded over base of the flange forms a bead which strengthens and stiifens the cover and at the same time improves its appearance. Y

In the illustrated embodiment of the invention, f

Figure" 1 is a perspective view of a circular slip cover taken yin vertical section through the middle of the cover, and

Figures 2 and 3 are detail sections showing modifications.

Referring to the illustrated embodiment .of the invention and particularly` to Figure 1, the cover which is illustrated as aslip cover is made of a paper disc. The edge portion of the disc is bent atisubstantially. right angles to the disc body 1 to form the usual flange 2. The paper at the base of the flange is bent back upon" itself at 3 to form a bead 4. It Will be noticed from the drawing the 1 the center of the can cover is shown as depressed to form an ornamental bead or ridge 5 around the top of the cover.

In Figure 2 is illustrated a modification in which an auxiliary disc 6`is inserted inside of the cover. The edge of the disc 6 fits into the fold 3 where the paper is folded back upon itself. In Figure 2, the center of the cover is shown depressed to provide the bead 5 around the top.

In Figure 3 is illustrated another modification in which an inner disc 6 is placed within the cover having its edge fitting in the folded back portion of the cover. The

auxiliary discs 6 may be used when it is desired to thicken and strengthen the top of the cover, or they may be omitted, as shown in Fi re 1.

Vhile the present invention has been specifically illustrated and described, it is to be understood that it is not limited .to the illustrated embodiment, but may be otherwise embodied within the scope of the following claims.

v We claim:

1. A paper container cover formed of a paper disc having its edge portion folded back. upon itself and then bent substantially at right angles to the disc body, and

an inner disc having its edge extending into JAMES E. ANNEN. GEORGE O. FROSTAD.
